Which respiration pattern involves gradually increasing then decreasing rate and depth with periods of apnea?

Which respiration pattern involves gradually increasing then decreasing rate and depth with periods of apnea?

• A. Cheyne-Stokes respirations
• B. Biot's respirations
• C. Kussmaul respirations
• D. Normal breathing

Answer: (A)

Cheyne-Stokes respirations are defined by a repeating cycle of progressively increasing and then decreasing breathing effort and tidal volume, followed by a period of apnea. The cycle often lasts 30 seconds to a couple of minutes, with the apneic pauses ranging from a few seconds to nearly a minute. This pattern arises from a delayed or unstable feedback response of the brain’s breathing control to CO2, and it’s commonly seen in patients with advanced heart failure, stroke or other brain injuries, and sometimes in dying patients. Because it produces a clear crescendo-decrescendo pattern with pauses, it fits the description you were asked to identify. Biot's respirations, in contrast, are irregular and unpredictable in both rate and depth, with periods of apnea that lack a repeating, orderly rhythm. Kussmaul respirations involve rapid, deep, regular breathing, often seen with metabolic acidosis, and do not feature the cyclical apnea pattern described above. Normal breathing remains regular in rate, depth, and rhythm without apneic pauses.
